In thread t=231, Melissa, I hope you have ideas on how to make "a" thin sheet of MDF that's the full length of THIS table, rigid enough to flip over intact.

t=2553 router's already trammeled.

It's been suspiciously quiet from Brighton for the past 24 hours. I expect momentous news. Either really good news, or that the gantry drove over his arms and he can't type on a keyboard anymore.

Loctite, followed with a dab of paint across nut and bolt so you can later see if it's loosening, and a note in your maintenance schedule to check that dab monthly?
